である。(Example) Next, the present invention will be explained in more detail with reference to the illustrated examples. In the figure, 1 is a porous base material for forming a combustion surface laminated on the surface of a shape-retaining member 2 such as a wire mesh, and 3 is a porous base material for forming a combustion surface. This is a porous surface layer formed on the upper layer of the porous base material 1. The porous base material 1 is made of heat-resistant fibers made of alumina-based or zirconia-based ceramics and a thermosetting resin such as phenolic resin with a particle size of 0.5.
It is preferable to use short ceramic fibers having a length of 1 to 5 mm as the heat-resistant fibers, which are a mixture of organic particulate matter of about 3 mm. The porous base material 1 has a porosity of 60 to 90%, and it is preferable that a base metal catalyst such as nickel or aluminum or a noble metal catalyst such as platinum or palladium be supported therein. On the other hand, the porous surface layer 3 is made of ceramic long fibers with a length of 10 mm or more and an inorganic binder, and has a porosity that is 5% or more larger than that of the porous base material 1. be. The thickness of the porous surface layer 3 is preferably about 20 to 60% of the thickness of the porous base material 1.The porous base material 1, which has excellent formability because it uses organic granules as a binder, is first shaped. A combustion part is created in which the porous base material 1 and the porous surface layer 3 are laminated in two layers by laminating them on the surface of the member 2 and then applying a mixture of heat-resistant fibers and an inorganic binder to the upper layer. It is possible to obtain a cylindrical or flat surface combustion burner having the following properties. Note that 4 is a gas mixture supply pipe, 5 is a gasket layer formed at the base of the gas mixture supply pipe 4, and 6 is a cavity inside the shape retaining member 2.

もある。(Function) With this configuration, if the mixture of hydrocarbon fuel gas and air is ignited while being supplied from the mixture supply pipe 4, the mixture will flow into the cavity 6 inside the shape retaining member 2. The flame spreads uniformly throughout the entire porous base material 1, passes through the inside of the porous base material 1, and then burns inside the surface layer or the porous surface layer 3 formed on the top surface of the porous base material 1. This results in surface combustion without causing any damage. At this time, since the main part of combustion takes place in the porous surface layer 3 with a low porosity, the organic particulates in the porous base material 1 are less likely to be burned away, and even if the organic particulates in the porous base material 1 Even if the heat-resistant fibers are liberated due to burning, the heat-resistant fibers are reliably captured by the upper porous surface layer 3, so that they do not scatter as powder and adhere to the object to be treated. Furthermore, since the combustion section is made of two layers, both of which are made of materials with low internal thermal conductivity, there is no risk of backfire, and high-load combustion can be performed. Furthermore, a combustion part of any shape such as a cylinder or a plate is formed using a porous base material 1 containing an organic binder and having good formability, and then a porous surface layer 3 is laminated on the top surface of the combustion part. This method also has the advantage that it is possible to obtain combustion parts of various shapes that could not be formed using conventional mixtures of inorganic binders and ceramic fibers alone.

Since it is possible to carry out high-load combustion without fear of sparks occurring, it is suitable as a heating source for heat treatment furnaces and paint drying furnaces where it is disliked that spark powder adheres to objects to be treated. Therefore, the present invention has extremely great practical value as it solves the problems of conventional surface combustion burners.
